Biomathematics Seminars

Our seminars are very informal, where many questions are asked, new ideas are tried on the blackboard, and free discussion is encouraged. All seminars are in English. The program is updated continuously, look out for new titles.

Time and place: Wednesdays 10:15 - 12, Exactum D123

All interested are warmly welcome!
